JOHN B. SPERRY, 0F AURORA, ILLINOIS, ASSIGNOR IO THE AMERICAN WELLWORKS.. OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS.

DEEP-WELL PUMP.

Application led October 12, 1912.

To all whom t may concern:

Be it known that I, JOI-IN B. SPERRY, a citizen of the United States,residing at Aurora, in the county of Cook, in the State of Illinois,have invented certain new and useful Improvements in Deep-Nell Pumps, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to pumps for lifting water from deep wells and hasto do more particularly with double acting pumps in which there are aplurality of pistons or plungers arranged to be reciprocated by suitablemechanism located at or near the surface of the ground, such forexample, as that shown and described in patent to Matthew T. and Mark C.Chapman, No. 677,438, dated July 2, 1901, although any other suitablemechanism for actuating the plungers may be employed.

The object of my present invention is to provide an improvedconstruction by which the effective stroke of the plungers may beincreased, and the capacity of the pump accordingly increased, withoutvarying the operating stroke of the actuating mechanism by which theplungers are reciprocated. I accomplish this object as illustrated inthe accompanying drawings and as hereinafter described.

IVhat I regard as new is set forth in the claims.

In the accompanying drawings, Figui-e i is a vertical sectional view ofthe upper portion of a well tube equipped with my improved pumpingapparatus ,'Fig. 2 is a similar view, being an extension downward of theparts shown in Fig. 1; Figs. and 4 are views corresponding with thoseshown in Figs. 1 and 2, but taken at right angles thereto; Fig. '5 is across section on line 5 5 of Fig. 1; Fig. 6 is a cross section on line 66 of Fig. 1; Fig. 7 is a cross section on line 7 7 of Fig. 2; Fig. 8 isa cross section on line 8 8 of Fig. 2; Fig. 9 1s a cross section on line9 9 of Fig. 4; Fig. 10 is a sectional view showing a modifiedarrangement of the lower end portion of the pumping apparatus; Fig. 11is a vertical sectional view showing a modiiied arrangement of the outerpump cylinder; and F 12 is a similar view, being an extension downwardof Specification of Letters Patent.

the arrangement shown in Fig. 11, illustrating the valve mechanism andpacking at the lower end of the pumping apparatus.

Referring to the drawings, in which corresponding parts are indicated bylike refern ence characters, l3 indicates the well tube or casing whichextends from the surface down into the well as far below the pumpingapparatus as may be desired.

14 indicates an outer cylinder which, in the construction shown in Figs.1 to 10, inclusive, is supported from its upper end and extends downinto the well tube. Said cylinder is provided at its lower end with anextension 15 of somewhat less diameter, which is connected thereto by ascrew coupling 16, as shown in Fig. 1. The extension cylinder 15 ispreferably made of brass, but it may be made of any other suitablematerial.

17 indicates a tubular plunger which is adapted to reciprocate in thecylinder 15 and is provided with packing-rings 18, of leather or othersuitable material, which are held in place and are expanded laterally bypacking-rings 19, of brass or other suitable material. As shown in Fig.1, the lower poi tion of the plunger 17 is expanded or enlarged to forma shoulder 20 on which the lowermost packing-ring 18 rests, and all theseveral packing rings are pressed together by a sleeve 21 and a ring 21asecured upon the upper portion of the plunger, as shown in Fig. 1. Asleeve 21 also serves as a means for connecting the plunger 17 with asuitable connection 22 by which said plunger is connected with a tubularplunger rod 23. The coupling 2i which is in the form of a spider, servesto connect the connection 22 with the plunger rod 23. Said plunger rodextends to the surface and is connected with the operating mechanism sothat it may be reciprocated.

25 indicates an upwardly opening valve at the lower portion of theplunger 17', which is preferably ofthe type shown inpatentto It. E. L.VHolmes, 990,359dated April 25, 191,1, said valve being normally seatedby a spring 26.

27 indicates a tubular plunger rod which extends up through the valve 25and plunger 17 and is connected with a solid plunger rod 28 by means ofa valved coupling 29, in the form of a cage which contains a ball-valve30 adapted to seat upon the upper end of the plunger rod 27. Preferablya bushing 31 is provided between the plunger rod 27 and the coupling 29,said bushing serving also as a seatfor the valve 30.

32 indicates a stutling-box fitted around the plunger rod 27 below thevalve 25, as shown in Fig. 1.

33 indicates an inner cylinder which is connected with the lowerportionV of the plunger 17, preferably by screw threads as shown in Fig.1, and eXtends down into the well preferably below the lowerl end of thecylinder 15.

34 indicates a second plunger which is connected with thelower end ofthe plunger rod 27, said plunger 34 being provided with a' centra-lvtube 35 which screws upon the lower end of the plunger rod 27, as shownin Fig. 2.

36-37 indicate leather and metal packing-rings mounted on the plunger34.

38 indicates passages in the plunger 34 which connect the tube 35*withthe interiorI of the cylinder 33 below the plunger 34.

39 indicates a pipe which extends downward from the lower end of theplunger 34, as shown in Fig. 2. Said pipe communicates by passages 40,as best shown in Fig. 4with the interior of the plunger around the pipe35, which space is indicated by 41 in Fig. 2. The construction of theplunger 34 is substantially the same as that shown in the Holmes patenthereinbefore referred to.

42 indicates a Lcoupling secured in the lower end of the cylinder 33,said coupling` having passages 43 through which water may flow from theinterior of the cylinder 13 into the lower portion of the cylinder 33.

44 indicates an upwardly opening valve which normally closes saidopenings, said valve being seated by a spring 45 and `being held inplace by a cage 46.

47 indicates a stufling-boX carried by the coupling 42 around the lowerportion of the tube 39, as shown in Fig. 2.

48 indicates a cylinder which is connected with the lower portion of thecoupling 42, below the passages 43, and extends down into the well.

' 49 indicates a third plunger which is adapted to reciprocate in thecylinder 48, and is also provided with suitable packing rings as in thecase of the upper plungers. Said plunger is tubular and is connected bya coupling 5() with the lower end portion of the tube 39. Said couplingcarries a valvecage 51 in which is carried a spherical valve 52 adaptedto seat in the upper end of the plunger 49, as shown in Fig. 2.

, rI'he plunger rods 23 and 28 are intended to be reciprocatedsimultaneously in opposite directions by means of the actuatingmechanism at the surface. It follows, therefore, that when the plungerrod 23 is moved down, as the cylinder 33 is connected with the plunger17, said cylinder will be moved down at the Same time. Furthermore, asthe cylinder 48 is connected with the cylinder 33 through the coupling42 the cylinder 48 will also be moved down. At the same time the pistonrod 28 being moved up will carry up with it the plunger 34, and thelatter being connected with the plunger 49 will move that plunger upalso. Opposite movement of the two plunger rods will effect oppositemovements of the parts connected with them. The result of thesemovements is to increase the effective stroke of the several plungersand thereby increase the volume of water discharged. For example, whenthe plunger rod 23 moves upward and the plunger rod 28 moves downwardthe plunger 34 will approach the valve 44, in the lower portion of thecylinder 33, twice as fast as if the cylinder 33 were stationary. rheupward movement of the cylinder acts to lift the water above the valve44 through -the passages 38 and tubes and 27 into the upper portion ofthe cylinder 22 and through it into the outer cylinder 14 from which itis lifted by the plunger 17. At the same time downward movement of theplunger rod 28 and the parts connected with it causes water to fiow upthrough plunger 49 into the cylinder 48 and up through the tube 39 andplunger 34 into the upper portion of the cylinder 33 and thence upthrough valve 25 and plunger 17 and connecting cylinder 22 into theouter cylinder 14. Upward movement of the plunger rod 28 lifts plungers49 and 34, and, as at the same time the downward movement of the plungerrod 23 carries the cylinders 33 and 48 down, the plunger 34 will moveaway from the valve 44 twice as fast as if either of the parts werestationary and will suck water up through the passages 43 into the lowerportion of the cylinder 33, whence it will pass through passages 38 andtubes 35 and 27 into connecting cylinder 22 and into the outer cylinder14. Furthermore the plunger 49 will approach the closed upper end of thecylinder 48 twice as fast, thereby forcing the water in said cylinderout through the tube 39. At the same time the plunger 17 will be movingdown to meet the plunger 34, in preparation for its neXt lifting stroke,thereby doubling the volume of water which Hows up through valve 25.

The practical effect of the pump in operation is as follows, assumingthe pump to be full of water: lhen the pump rod 23 and the cylinder 33are moved downward, the plunger 34 moves upward, and consequently saidplunger, and the valve 44 car ried by the cylinder 33, move away fromeach other by a distance equal to twice the stroke of either of saidparts. Assuming 1,208,038 Vit,

the stroke to be three feet, it follows that the plunger 34 and thevalve 44 will have been moved apart six feet. In this movement, waterwill have entered the cylinder 33,.through passages 43, lling the sixfeet of space in said cylinder thus provided.

i" While the plunger 34 has been rising the distance of three feet, andthe cylinder 33 has beendescending the same distance, six feet of waterwill have been -forced up through the valve 25, but only three feet ofthe water will have been discharged, as the valve` 25 will have beenmoved down three feet, thereby making an actual lift of only three feetof water by these parts. The amount of water discharged, however, willhave been increased by the, action of the plunger 49 and the check valve52, in thecylinder 48, since said plunger 49 will have been moved upthree feet, while the cylinder 48 will have been moved ldown three feet,thus forcing six feet of water up through the tube 39 to the surface ofthe ground. Assuming three feet of water to be a unit, it will beapparent, therefore, that by this action three units of water will havebeen discharged. Opposite movement of said parts also acts to dischargethree units of water in the following manner: When the cylinder 33 movesupward, and the plunger 34 moves downward, the six feet of water betweenthe plunger 34 and the valve 44 is forced up through passages 38 anddischarged above the valve 30, at the upper end of the tube 27. At thesame time the cylinder 33 will have risen three feet, thus dischargingone unit of water lying above the valve 25. The pump thus dischargesthree units of water on each stroke.

In the construction shown in Fig. 10 I have. illustrated a modificationin which the lowermost plunger 49 is omitted. In view' of the omissionof the lowermost plunger the cylinder 48 is also omitted and I employ ahead 53 which is substantially the same as the coupling 42, but isslightly modified so as to adapt it to lit more closely into the lowerend -of the cylinder 33. With this construction a check valve similar tothe valve 25 is provided above the plunger 34 to prevent downward flowof water through said plunger. TWith this modified construction thevolume of water pumped is approximately four times as great as in asingle acting pump of like character.

It will be noted that the weight of the column of water being lifted issustained by the pump rod 23 and cylinder 14. As it is sometimesdesirable to relieve these parts of such weight I may employ a cylinder54 which is substantially the same as the cylinder 15 except that it ispreferably fiar-ed at the top and is provided with a downward extension55 which carries at its lower end a conical sleeve 56, shown in Fig. l2.Said sleeve fits into a conical packing sleeve 57 which fits into aconical sleeve 58, carrying wedges 59 adapted to engage the well tube 13and be held in place therein by wedging contact. This supporting deviceis shown and described in patent to Chapman and Chapman, No. 677,438,hereinbefore referred to. The packing sleeve 57 tightly closes the spacebetween the lower end of the cylinder 55 and the well tube.

60 indicates a valve-cage in the tapered sleeve 56, said valve-cagehaving a spherical valve 6l which opens upwardly and forms a check-valveto permit r'upward iiow of water, but prevent downward flow thereof. Bythis construction when the pump is full of water the weight of thecolumn is sustained by the foundation or support 58.
